Be it known thatwe, CHARLES 3"..NnLsoN, OLAF OsTLiN, and EDWIN l?.rSWANGREN, citizens oi the United States, residing in Ma 'vvood, in thevcounty' of Cool; andv State of llinois, have invented a new and usefulvlinproveiiient in Double-Scanning Machines, ofrwhi'cli the folloyvingisa specification.

Our invention relates toiniprovements in 'double seeming machines forseainiig can heads-to can bodies. `The object of our invention is toprovide an automatic, continuous,

preferably having six can head receiving faces It, and which rotatescontinuously and serves to deliver the can heads one by one to the shortcan headfeed'chute C1. To prevent the canbody from dropping or being fedfrom the can body chute G into the pocket of the carrier B as it passesunder the can bodyvchute, unless there is also 4a can head X in theshort can lnead chute C1 readyto be 'also fed to the er rier and thusprevent the flange of the can body being seamed onto the can head chuck,as would `otherw1se occur, we provide e can body feed controllerl,preferably a movable ingerior lever, adapted to be projected into thecan body chute, and the operation of which is controlled by the presenceor absence of a' can head on the face of the supplemental feeder Ilimmediately above the can head .chute C1. To accomplish this, #each ofthe` ipo can headseats on, the supplemental feeder H2 is provided with amovable pin zor device tl havlng a member it adapted to engage the canhead onthe can head seat or face .of the delivery wheel ll2 if one ispresent; and if no can head is present, to be further moved and engagethe arm K2 of the operating lever K2 of the 'can body feed controller Kand thus cause the rotation of 'the supplemental can head feeder H2 tooperate the can body feed controller l. The pin or movable device h1",as the supple-mein tal feeder H2 revolves, engages a light spring` H onthe stationary frame.

lf a can head' is present on the face` of' the supplemental feeder, thespring H2 is pushed out ofthe `Way by the pin or movable `stop deviceh1",

the canhead thus preventing therpin ft2 being moved byl the spring H,and thus also preventing said pin h1 from engaging the can body feedcontroller operatingleverl 1. f, however, no can head is present on theface of the supplemental feeder H2 directly above. the short can headchute C2, the vspring H2 will push the pin h1" in suliiciently to causeit to engage the operating lever o the can body feed controller K andthus cause said controller to arrest or prevent the grav- 85 .4 ralityof sets of double seaming rollers e carrier when no can head is presenton one of the can head seats of the supplemental feeder or deliveryWheel H2 and the spring H3 consequently slides the pin h1 intopositionto engage the operating leverv Kf .of the can body feedcontroller K, the pin'hlisautomatically returned to its normal positionas the delivery wheel H2 fur-f ther rotates by means-of a stationary camx It on the frame of the machine.
